TUYERE.

SPECIFICATION forming part of Letters Patent No. 295,548, dated March 25, 1884:.

Application filed August 6, 1883.

Be it known that I, JACOB F. EARLY, a citizen of the United States, residing at Kipton Station, in the county of Lorain and State of Ohio, have invented a new and useful Improvement in Tuyere-Irons, of which the following is a specification.

My invention relates to tuyere-irons surrounded with a curre'nt of water; and my object is to so construct the same as to be more efiectual and more convenient in setting and using. I attain these objects by the mechanism illustrated in the accompanying drawings.

Figure 1 is a top view of my invention. Figs. 2 and 3 are side views, and Fig. 4 is a vertical transverse section, of the same.

Similar letters referto similar parts throughout the several views.

A represents the body of the tuyere, and it consists of a water-tight annular chamber, 13, the inner walls, 0, forming a passage-wayor throat, D, in which is fitted a concave valve, E, attached to the upper end of the straight stem F. The lower end of said stem is provided with a lever, G, whereby said valve is raised or lowered at will for closing or opening said throat. The valve, as will be seen,

is made to fit closely therein at the top, so

To the under side of the body is attached an ash-box, I, communicating directly with the 40 passage-way D.

J is an air or blast pipe connected with that from the blower.

The inner chamber, D, has four or more lugs, K K, secured to its walls, forming ways for the valve E to slide on, and when said valve is lowered toallow free passage for the blast with very slight resistance from said valve E or walls 0. Said lugs K are situated at equal distances from each other and attached to No model.)

[said walls O, the said lugs of any suitable thickness and breadth to afford free passage for the blast between their sides and extend.

of the throat-D. The valve E is circular in form, and of such size as will fit in between the inside edgesof said lugs K. In the center of the top of the body A is a circular opening communicating directly with the throat D, the edges of the top in which said opening is made extending over the top of said lugs K a sufficient distance to form a seat for the valve E, and thereby shutting off all blast by closing said valve.

The operation of my invention is as follows: The tuyere is built into a forge in the position shown in Fig. 2, so that the pipes H and J will extend back of the fire-place. The tuyere thus forms the bed on which the fire is built. The chamber B is filled with water by connecting the pipes H with a reservoir at a suitable height. with a blower, the blast passes through the chamber D, and is fed to the fire by opening the valve E by means of the lever G. ,By reason of the lugs or ways K K on the sides of the walls 0, said valve E, when lowered or dropped down, is held at all times directly under the center of the opening in the top of the body A, and prevented from falling or leaning to one side or the other, and the blast thereby has an equal opening on all sides of said valve E, and escapes uniformly around its edges, instead of more on one side than the other, as would be the case without any supporting-lugs for said valve. The volume of air is regulated by means of the lever G being raised or lowered asdesired, and thereby opening or closing said valve E.

By keeping the chamber D constantly filled with water, the tuyere cannot as soon burn out as if used without being brought intocontact with water. All dirt and ashes falling through the chamber D are deposited in the ash-box, and can be removed therefrom by drawing a slide, L. r

I am aware that tuyere-irons have heretofore been invented with an annular waterchamber, valve-pipes, ash-box, and throat, as

The pipe J being connected described in a patent issued to me December 7, 1869, numbered 97,507, and herein I make no claim thereto.

What I claim as new, and desire to secure 5 by Letters Patent of the United States, is

A tuyere-iron constructed with a Waterchamber, B, throat D, ash-box I, valve E, and pipes H and J, in combination with the lugs K, attached to the Walls of the throator passage-way D, and straight stem F, and lever 10 G, operating thevalve E, all as above set forth, and substantially as described.
